Title: Nobuo Furumoto: Innovator in Satellite Technology

Introduction

Nobuo Furumoto is a distinguished inventor based in Sunnyvale, CA, known for his contributions to satellite technology. He holds 2 patents that showcase his expertise in attitude control and navigation systems for high-resolution imaging.

Latest Patents

Furumoto's latest patents include an "Attitude Control and Navigation System for High Resolution Imaging." This innovative system consists of a satellite position and attitude reference system utilizing Global Positioning System data. It features an onboard computer that analyzes and generates position and attitude-dependent instructions. The attitude control system adjusts the spacecraft's attitude in response to these instructions, while the imaging system generates image data for transmission. A ground-based image data receiver assembles and processes the image data, compiling sequential images into a mosaic of the target. Notably, the onboard computer delays the generation of attitude control instructions during image data capture to prevent distortion from spacecraft movement.

Another significant patent is the "Dynamic Bias for Orbital Yaw Steering." This method and apparatus are designed for steering low-earth-orbit communication satellites that require sun orientation for solar power accumulation. The approach employs momentum bias to maintain nadir pointing while adding yaw-steering moments for sun-tracking attitude control. The method involves open-loop momentum decoupling to correct steering torque and closed-loop attitude compensation to address perturbations in accordance with control law definitions.
